Rich Peas Soup

Ingredients

Directions

Prepare the soup

  1. Drain the soaked peas and place them in a large soup pot with the brown gravy stock.

  2. Boil gently for 30 minutes.

  3. In a pan, fry the sliced onions, carrots, and turnips in butter until browned.

  4. Add the fried vegetables to the soup and stew until the peas are reduced to pulp.

  5. Season with salt and cayenne pepper, then boil for 2-3 minutes.

  6. Pass the soup through a sieve, pressing the vegetables to extract flavor.

Finish and serve

  1. In a clean saucepan, add the strained soup and adjust thickness with fresh stock if needed.

  2. Boil quickly to reduce if too thin, then add the sliced celery and cook until tender.

  3. For added flavor, mix curry powder with a few spoons of soup and add it when the soup begins to boil.

  4. Serve the soup hot with small fried sippets on the side.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Yellow split peas
Break down into pulp to give the soup its body and thickness.
Brown gravy stock
Provides the liquid base and savory depth for the soup.
Onions
Fried in butter until browned, adding sweetness and savory aroma.
Carrots
Fried with onions and turnips, adding sweetness and color to the soup.
Turnips
Fried until browned, adding earthy flavor and body to the soup.
Celery
Cooked until tender at the end, adding fresh, vegetal aroma.

The step that matters

Passing the soup through a sieve. Pressing the cooked vegetables and peas through the sieve extracts their starch and flavor, which thickens the soup. Peas that are not fully softened will stay grainy and give a rough texture.

Swap the peas

How well each one fits the dish's main ingredients (onion, carrot, turnip, butter, pepper, celery):

  1. Beansfits better
  2. Lentilsfits better
  3. Chickpeafits better
  4. Peasthe original

Fit is the average pairing score against onion, carrot, turnip, butter, pepper, celery. Candidates are from the same food group and used in at least 100 recipes.
